    Is this a good sponge filter for a quarantine tank? Or a regular tank? And can someone explain to me how these things work. For the life of me I cant figure out how water is pulled in and forced through the media... in any sponge filters like this for that matter. Thanks.

    I believe that the airstone that you put at the center of the sponge filter simply creates a low-pressure which in turns sucks water in through the sponge.
